client :

   * now custom CommandServlet URL path can be specified (typically when deploying
etlconnector-alfresco3.1.3+'s overriden ContentImporterCommandServlet along the

view:associations (but to no harm in most cases)
   * improved test framework, added test of duplicate child name error case

moved server side to 1.2
